We have developed a compact antenna for wireless applications with a new shape and special attribute. It is a dual‐band antenna with a second harmonic characteristic. The antenna has a special shape of the dielectric resonator with metamaterial meandered composite right/left‐hand (CRLH) structure. The Microstrip ring antenna is the right‐hand part. We used the Microstrip meandered line via inductance for the unit cells to achieve a circular polarization and to change the current distribution at the surface of the antenna. We added a parasitic ring to the antenna to achieve the second harmonic resonance. We have connected three unit cells at the 120° angle. This special shape provides the circular polarization and compact size. The antenna has quad‐band at the first harmonic, and the resonances occurred at 2.25 and 2.8 GHz. The second harmonics happened at 4.5 and 5.6 GHz.
